Abstract: 1,124,036. Rollers. RANK XEROX Ltd. 11 Oct., 1965 [14 Oct., 1964], No. 43034/65. Heading F2U. [Also in Division G2] A resilient pressure roller, particularly a lower, pressure roller of a xerographic heat fusing device, comprises a rough-outer-surfaced resilient cylinder 12 of silicone rubber moulded and bonded on a steel core 11, fluorosilicone rubber cylinder-end ring seals 13, 14 bonded to the core, and a protective sleeve 17 of fluorinated ethylene/propylene copolymer, a material repellent to sticky substances, placed over the cylinder and seals and secured thereto by a silicone rubber adhesive and by heat shrinking. The heat fuser, effecting fusing of a toner image on a support material, comprises an upper roller 1 and the lower pressure roller 10 between which rollers the support material is advanced image side up. The upper roller is provided internally with a heating element. To prevent toner offset on to the upper roller, the peripheral surface of the latter is covered with a coating of fluorinated ethylene/propylene and a thin film of silicone fluid is applied thereto by a wick 5.

Title: Improvements in or relating to Thermally Controlled Actuating Devices.
IPC: G05B19/07
Filed: 1966-09-27
Abstract: 1,158,806. Valves. DANFOSS A.S. 27 Sept., 1966 [19 Oct., 1965], No. 43143/66. Heading F2V. [Also in Divisions G1 and H1] A thermally controlled actuating device includes a heating coil 12, a bimetallic actuator 1, and a bimetallic compensator 2, wherein bimetals 1 and 2 are connected by a bearing 3 carrying an actuating lever 9 and rotating about a fixed pivot 4. The free end of bimetal 1 bears against a fixed stop 5 and that of bimetal 2 actuates a plunger 6 of respectively normally closed and normally open microswitches 7 and 8. The free end of lever 9 acts upon the plunger 10 of a manually closable switch 11. Switches 7 and 11 are in series with the coil 12 which is supplied by A.C. input 13, and terminals 14 are connected across the device to be controlled. When switch 11 is closed and current thus supplied to coil 12, bimetal 1 is heated and bends and parts 3, 2, 9 rotate about pivot 4 and bimetal 2 depresses plunger 6 to open switch 7 and close switch 8. This opens the heating circuit. Due to stored heat bimetal 1 bends more. After a time delay, bimetal 2 attains the temperature of bimetal 1 and bends to release plunger 6 (Fig. 3). Thus a new cycle can commence. At each cycle, as its temperature increases, bimetal 1 bends more and plunger 10 is depressed more till after a given number of cycles switch 11 opens and the system is disconnected. Switches 7, 8 may be replaced by a single change-over switch. Plunger 10 may alternatively operate a valve, an optical indicator, or an acoustic signalling device.

The apparatus is adjusted such that a piece of dough is at all times subject to flattening or edge shaping or rolling up. The shaft 10 is adjustable horizontally and vertically; the flaps have stops 11 which determine their lowermost positions, their uppermost positions being determined by their contact with the leading edge of the member 12. The latter is adjustably mounted by telescopic spindles 16, 17 eccentrically attached at their upper ends to rotatably mounted discs 18, 19 actuated by threaded shafts 20, 21.

Title: Improvements in and relating to variable-speed transmissions for machines
IPC: F16D48/02
Filed: 1959-12-23
Abstract: 899,451. Change-speed and clutch control. BERGHAUS, B. Dec. 23, 1959 [Dec. 23, 1958], No. 43720/59. Class 80 (2). A transmission comprises a steplessly variable gear and a main clutch and has a common control member which, when moved from a neutral position in which the clutch is disengaged and the gear is in its lowest ratio, first gradually engages the clutch and subsequently increases the gear ratio. As shown, the variable speed gearing is of the adjustable cone pulley type and drives through fixed reduction gearing the input shaft of a multi-plate clutch 6, the output shaft of which drives a machine 10. The fixed reduction gearing and the clutch 6 are immersed in an oil bath provided by a casing 4. A control pedal 7 actuates a cam slide 12 which is biased upwardly to the neutral position shown in which a pump 11 discharges through a valve 8 to exhaust. On moving pedal 7 downwardly a cam surface a increases the loading of valve 8 so that the pump pressure gradually increases The pump permanently supplies liquid to the clutch engaging servo, so that the clutch engaging pressure gradually increases. After full clutch engagement has been obtained, further depression of the pedal causes a cam surface b to actuate a follow-up servo-arrangement 9 controlling the output cone pulley so that the effective diameter is reduced. The input pulley automatically accommodates itself to the diameter of the output pulley.

Abstract: 1459017 One-way-acting detents AMERICAN SAFETY EQUIPMENT CORP 9 Oct 1974 [10 April 1974] 43810/74 Heading F2E When a pawl 28, Fig. 5, is urged towards a ratchet wheel 22 by counter-clockwise swinging of an inertia pendulum 32 (e.g. to arrest rotation of the reel of a safety belt, Fig. 1, not shown), the pawl tip may initially make contact with a tooth tip, and the pawl may in consequence be deflected from the tooth path by subsequent rotation of the ratchet wheel. Unchecked rotation of the ratchet wheel 22 which might otherwise ensue is prevented by engagement with it of another pawl 45 which is pivoted into position by an embossment 50 on pawl 28. To effect this movement, pawl 28 is constrained, by engagement of a pin 36 on its underside with a depression in an actuator 34 connected to pendulum 32, to be pivoted clockwise by the deflection.

Suggested synthetic fibres are polyacrylonitrile, polyamide, polyurethane, polyvinyl and polyterephthalic acid ester fibres.  In a mixture of fibres, a preferred ratio of natural to synthetic fibres is 70 : 30. Suggested components of the binding agent are vinyl polymers, e.g. PVC, polyalkenes, e.g. polyethylene or polypropylene, dienes, e.g. polybutadiene, acrylic esters and derivatives thereof, e.g. methacrylic acid butyl ester, amides of e.g. polymethacrylic acid and aminoplasts, e.g. formaldehyde precondensates of melamine.

A method of producing physical test specimens from metallic or non-metallic bar stock comprises supporting a cutting tool 21, such as a grinding wheel or milling cutter, for rotation with its cutting edge adjustably positioned between an underlying work-table 23 and a guide sleeve 25 positioned above the work-table, supporting a workpiece 27 for rotation between the work-table and an overlying guide template 26 having a guide surface 28, independently rotating both the tool and workpiece, progressively reducing the spacing between the guide sleeve and cutting edge of the tool, and moving the rotating workpiece to and fro endwise while maintaining the guide surface 28 in engagement with the guide sleeve 25. In apparatus for carrying out the method, the cutting tool 21 is belt driven from a motor 31 and is adjustable relative to the guide sleeve 25 by a lead screw 34 having a hand wheel 22. The periphery of the tool is semicircular and lies within the guide sleeve which is partially cylindrical and carried by a fixture 46 from the work-table 23.

The dielectric of a capacitor which may be flat (Fig. 1, not shown), tubular (Fig. 2, not shown) or stacked (Fig. 3, not shown) comprises an insulating barrier layer 42 on the surface of conductive perovskite crystallites 41, these having the formula (Ba 1-x M<SP>II</SP> x )O.z(Ti 1-y M<SP>IV</SP> y )O 2  where M<SP>II</SP> is one or more of the metals calcium, strontium, magnesium and lead, and M<SP>IV</SP> is zirconium and/or tin and z is 1À005 to 1À05, the material containing at least two doping substances, at least one of which produces n-type conductivity within the crystallite, and the other is a p-type dopant acting in the surface layers, the amount of n-type dopant being greater by a factor of 1À25 to 1À5 than the maximal doping quantity, and the amount of p-type dopant being 0À01 to 0À15% by weight. The n-type dopant may be antimony, niobium or bismuth; the p-type dopant may be copper, iron or manganese. The excess of the tetravalent constituent of the perovskite may be obtained by wet-grinding stoichiometric proportions of precursors and firing, or by dry grinding a mixture containing the required excess. The size of the crystallites may be 20 to 300 Á. The high proportion of n-type dopant increases the amount of p-type dopant which can be accepted without impairing the dielectric constant. The voltage dependence of the dielectric constant varies with the amount of p-type dopant.
